Guys. I need so advice.

I have gained exactly 30 pounds. I am 28 weeks. My midwife told me at my last appointment I needed to slow down. I have gained 10 pounds in only a month. I don’t understand how.

I’ve only eaten 1700 calories a day. I’ve been going to exercise 4 nights a week. I’ve cut out pop completely. Now when I go back tomorrow I’m going to get a lecture and I’m completely ashamed. I’ve gained 10 pounds in one month!

What did you guys do to slow down weight gain? I promise i’m not eating badly!
